Visuomotor integration (VMI), the use of visual information to guide motor planning, execution, and modification, is necessary for a wide range of functional tasks. To comprehensively, quantitatively assess VMI, we developed a paradigm integrating virtual environments, motion-capture, and mobile eye-tracking. Virtual environments enable tasks to be repeatable, naturalistic, and varied in complexity...
Nowadays, visual object recognition is one of the key applications for computer vision and deep learning techniques. With the recent development in mobile computing technology, many deep learning framework software support Personal Digital Assistant systems, i.e., smart phones or tablets, allowing developers to conceive innovative applications. In this work, we intend to employ such ICT strategies...
This paper proposes a multi-lingual enhanced Rapid Serial Visual Presentation (RSVP) system named “MulLinR,” which is an attempt for language-specific problems of existing RSVP tools. We design and build a prototype system, which currently only supports Japanese, and experiment with variation of presentation time intervals. Experimental results suggests 400 milliseconds is the most suitable time interval...
The aim of the mobile app "Zirkus Empathico" is to strengthen socio-emotional competences in pre-and primary school children. It's holistic and natural training concept is based on current results of empathy research. Pilot testing of the app revealed it's good usability and comprehensibility. The effectiveness of "Zirkus Empathico" is currently investigated in a longitudinal clinical...
The trends are reviewed in the development of unmanned transport systems. There is highlighted an increasingly important part of various range vision/location systems. There is described an architecture of the on-board computer network supplying information to the control systems of the mobile vehicles with the enhanced level of independence and totally unmanned. The proposed architecture provides...
Nowadays the mobile devices energy consumption has become a very serious issue. Due to the fast growing mobile industry the current devices usually contain wireless (Wi-Fi, 3G, 4G and Bluetooth), GPS and other heavy network sensitive technologies. The cell battery manufacturers usually cannot keep the pace with this fast altering environment and demands, hence the devices get inappropriate battery...
The advent of the mobile Internet era makes people's lives more and more dependent on the network, and users of the App requirements are increasing, not only functional requirements, focusing on ease of use, aesthetic needs, etc., which are each App developers and designers need to consider.
When interacting with virtual objects through haptic devices, most of the time only one hand is involved. However, the increase of computational power, along with the decrease of device costs, allow more and more the use of dual haptic devices. The field which encompasses all studies of the haptic interaction with either remote or virtual environments using both hands of the same person is referred...
With the increasing popularity of mobile technologies, users today are able to access information from virtually anywhere. Examples include localization via the Global Positioning System (GPS), Internet access through cellular and WiFi networks, etc. Using assistive technologies, people with disabilities can live more independently than ever before. However, most of the current mobile applications...
In this paper, we present the issues to be addressed and the practical solutions to these issues in a mobile application framework for reading and displaying musical scores enhanced to assist the visually impaired in reading and perform the pieces. This framework, currently operating on MusicXML input files, provides the structures and methods for developers to adapt for other music encoding file...
This article consists of a collection of slides from the author's conference presentation. Presents an overview of Mataio, a company that provides products and services in the field of augmented reality and computer vision. Some of the specific topics discussed include: corporate structure, product launchings, markets served, and major areas of technnological innovation in the field.
In mobile video applications, where unreliable networks are commonplace, corrupted video packets can have a profound impact on the quality of the user experience. In this paper, we show that, in a wide range of operating conditions, selectively reusing data resulting from decodable errorneous packets leads to better results than frame copy. This selection is guided by a novel concept that combines...
To create mobile applications, technical skills in informatics are needed. However, visual interface design is the key selling points in applications. Visual designers usually have little proficiency in neither informatics knowledge nor technical skill. Therefore, visual designers have some level of dependency on information engineers to create a mobile application.
Emerges in the sophistication of modern mobile devices encourages re-evaluations of mobile application design principles that were ideal only several years ago. As well, several mobile application design principles for facilitating collaboration are proposed. This paper then presents a system design that addresses all the discussed principles, creating a virtual meeting area in which participants...
Changing business environments, increasing complexity of industrial products, and an aging workforce are some of the challenges that have to be faced in the industrial field service area. In this paper, we present some application scenarios of bar codes in industrial field service and evaluate the suitability of existing 2D bar code software development kits to be utilized in the described scenarios...
Tourism studies have noted that insufficient attention has been paid to the experience and practices of the tourist. Tourism research does not help to explain the nature of modern mass tourism. The most detailed research that has been done is tourist information seeking, but the literature has tended to avoid detailed qualitative description, focusing more on broad categorizations of tourist practice...
Recent advances in mobile, wireless, and sensor technologies provide new possibilities for supporting learning activities that can be spatially distributed and incorporate different physical and environmental sensory data. In this paper, we present our technical efforts in relation to the design and implementation of mobile and web applications that integrate sensory data used to support inquiry-based...
A new error concealment technique based on the coding modes is proposed for H.264 video sequences. The motion-compensation modes (i.e., block-partitioning types) of surrounding macroblocks are employed to predict the mode of a lost macroblock. This adaptive selection mechanism is combined with a refined set of candidate motion vectors. Experimental results show that the proposed method, as compared...
The theory solution to embedded mobile database is defined not only by the study of embedded technology, but also by the confusing need for mobile technology. In our research, we verify the simulation of access points, which embodies the structured principles of embedded mobile database on mobile agent. In order to accomplish this mission, we propose an analysis of embedded mobile database based on...
